Hello I'm new to Modifying PSP's and my friend modified mine to devhook0.46 (while i wasn't there to see what he did) and i tried to change it to 0.52. i followed all the steps but for some reason devhook is not an option i can click on when i go to the games section on my psp. all i have as an option there is psardumper and corrupted data. I'm really not that good at this stuff but the guide seemed really straight forward so I thought i would give it a shot. please help me out, hopefully i did not delete a file that i was not supposed to. thanks in advance to anyone who responds.
